Optical properties of the iron-based superconductor LiFeAs single crystal
We have measured the reflectivity spectra of the LiFeAs ( T _c = 17.6 K) single crystal in the temperature range from 4 to 300 K. In the superconducting (SC) state ( T < T _c ), the clean opening of the optical absorption gap was observed below 25 cm ^−1 , indicating an isotropic full gap form...
